Understanding the basics of setup and hold timeDeepak Behera, Karthik Rao C.G. and Deepak Mahajan, Freescale Semiconductor, April 19, 2012Setup and hold times are treated as intrinsic properties of an element. However, it is the very existence of setup and hold time that often confuses us. Here are the cause of setup and hold time within a sequential element (flip-flop) and a look at the operation of the flop. More

New power semiconductor technologies challenge assembly and system setupsDr. Gerhard Miller, Infineon Technologies, Neubiberg Am Campeon, Germany, April 16, 2012While power density and performance rise, higher current densities require operating temperatures up to 200° C and faster switching to prevent losses, assemblies and system setups can't cope. Taking advantage of improved electrical properties requires thermal and electrical assembly technologies featuring very low stray inductances with a 10x to 20x better load-cycling capability at a higher temperature swing.

Optically isolating an I2C interface: Beware of nonlinear propagation delaysEric D. Blom, Senior Design Engineer, IXYS-Clare Inc., April 3, 2012The usual model of an I2C open-drain bus as a simple, shared pull-up resistor is not instantaneously valid when using bus isolators exhibiting real-world propagation delays. If the delays are not considered in the design of the hardware, then there can be unexpected consequences. More
